A representative for Kelly Osbourne has played down reports suggesting the reality TV star has been diagnosed with epilepsy after suffering a seizure on Thursday. The daughter of Ozzy and Sharon Osbourne was hospitalized in Los Angeles after collapsing on the set of her show Fashion Police last week. She remained under observation at Cedars-Sinai Medical Center over the weekend as doctors continued to investigate the cause of her health scare, but her spokesperson claims any rumors alleging she suffered an epileptic fit are premature. The rep tells People.com, “There is absolutely no confirmed diagnosis regarding Kelly’s condition at this time. She is under a doctor’s care and they are continuing to run tests. “Kelly is fine and thanks everyone for their continued support.” The 28 year old’s health crisis is the latest to hit the Osbourne family – Kelly’s younger brother Jack was diagnosed with multiple sclerosis last year.
